I built a AT screen and placed a baffle wall behind it. Google THX Baffle wall. Anyway the speakers I am using behind the screen have 5 1/4 woofers. The baffle wall lowers the bass of the speakers so they can reproduce an octave lower than they would if they were sitting on a shelf. I have used Audessey XT32 to equalize the system and Audessey has the speakers crossed over at 60 hz. Not bad really. My IB subs bring up the bottom end quite nicely.
The trick is not to use speakers with a port on the back if you build a baffle wall. Ports in the front are fine. A lot of people will talk about how the whole system needs to be engineered to work right. Well, fine, but I like to experiment. It has worked out very well for me without hiring any audio engineers. I figured XT32 would do the work of the equalizing for me. I agree with Bigmouth. Don't give up your vision. I will add to that don't let people scare you out of what you want to do in YOUR theater room. If you don't like the results, start over.
